摘　　要：通过对梁峁顶黄土立地类型,阳坡、风沙土立地类型,缓坡阶地类钙层黄土立地类型,缓坡阶地风沙土立地类型4种立地类型的5种造林模式的研究分析,提出了适宜半干旱风沙区典型立地类型的优化造林模式以及小叶杨成过熟林(小老树)的最佳更新改造模式。Five afforestation models were studied on 4 site types,involved ridge,replat,top site type,sunny slope and sand soil area site type,gentle slope terrance with calcium soil site type,gentle slope terrance with sand soil site type.For semiarid sand site type,the optimum afforestation model and regeneration method of overmature simon poplar trees were put forward.
